Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 86 % of all devices are better.This means that the measured response time is worse than the average of all tested devices (26.7 ms).

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 76 % of all devices are better.This means that the measured response time is worse than the average of all tested devices (42.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM detected

119000 Hz

80 % brightness setting

210 cd/m² brightness

The display backlight flickers at 119000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 80 % (210 cd/m²) and below. There should be no flickering or PWM above this brightness setting.

The frequency of 119000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

Flickering occurs even at high brightness setting and may have an effect on the user during everyday use.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.
